Varieties of aluminum powder coatings


Aluminum powder coating is the most important kind of metal powder coating. According to the appearance of the film, the metal aluminum powder coating can be divided into metal flash and metal coating powder coatings with smooth coating film, and the powder coating with textured pattern, hammer pattern and metallic luster texture. The film forming materials that can be used in metal aluminum powder coatings are epoxy, polyester epoxy, polyester, polyurethane and acrylic resin, etc. the main varieties used in China are polyester epoxy and polyester resin type metal aluminum powder coatings.


(1) Metal flash powder coating is a kind of powder coating made by adding non floating metal flash aluminum powder to the bottom powder of powder coating. After the coating is solidified into a film, the reflection of light by the metal flash aluminum powder evenly distributed makes the film flash effect.


(2) Metal coating powder coating is a kind of powder coating made by adding floating aluminum powder to the bottom powder of powder coating. After the coating film is solidified, due to the metal aluminum powder completely covering the coating surface, the appearance of coating film similar to "electroplated coating or polished stainless steel" is formed.


(3) Metallic pattern powder coating is a kind of powder coating made by adding metal aluminum powder and pattern agent to the bottom powder of the powder coating. When the coating film is solidified, due to the influence of the pattern agent on the surface tension, the silver pattern of metal aluminum powder is formed on the surface of the coating.


(4) Metal hammer pattern powder coating is a kind of powder coating made by adding aluminum powder and hammering agent to the base powder of powder coating. The Silver Hammer pattern is formed after the coating film is formed and solidified.


(5) Metallic luster texture powder coating is a powder coating made by adding aluminum powder and texture agent (sanding agent or wrinkle agent) in the bottom powder of powder coating. After the coating film is solidified, due to the effect of aluminum powder and texture agent, the appearance of metal luster texture coating film is formed.
